The Surprising Truth About Pure Spirits
At the core of the matter, the sugar content of both whiskey and tequila is negligible when consumed straight from the bottle. This is a direct result of the distillation process, which separates alcohol from the fermented mash, leaving behind residual sugars. For anyone monitoring their sugar intake for dietary reasons, this is excellent news. The misconception often arises from the final presentation of the drink—the cocktail—not the spirit itself.
How Whiskey is Stripped of Sugar
Whiskey is distilled from a fermented mash of grains like corn, rye, barley, and wheat. The process begins with malting, where grains are soaked and begin to germinate, creating enzymes that convert starches into fermentable sugars. During fermentation, yeast consumes these sugars, producing alcohol. Finally, the liquid is distilled, a heating process that purifies and concentrates the alcohol. This crucial step leaves the final spirit with a sugar content that is practically zero. Even though aging whiskey in charred oak barrels imparts sweet-tasting notes of caramel and vanilla, this is a flavor profile drawn from the wood, not added sugar. A standard 1.5-ounce shot of straight whiskey contains about 105 calories and no carbs or fat.
Why Tequila Also Has No Sugar
Similarly, high-quality tequila is made from the blue agave plant and, after distillation, is sugar-free. The process involves harvesting the heart of the agave plant, the piña, and cooking it to convert its complex carbohydrates (inulin) into fermentable sugars. The sugary liquid is then fermented and distilled, with the distillation process removing all residual sugars from the finished product. This is true for all 100% agave tequilas, from unaged blancos to aged añejos. A 1.5-ounce shot of 100% agave tequila contains around 97 calories and no carbs, fats, or sugars.
The Critical Exception: Mixto Tequilas and Flavored Spirits
While 100% agave tequila is sugar-free, it is crucial to be aware of 'mixto' tequilas. These are not made entirely from agave and can contain up to 49% other sugars, along with flavorings and additives. Similarly, flavored whiskeys, such as those with honey or cinnamon, are sweetened and contain significant amounts of added sugar. Always read labels carefully and opt for pure, unflavored spirits to avoid hidden sugars.
The Biggest Culprit: Sugary Mixers
The real source of high sugar content in many cocktails is not the base spirit, but the mixers. A single margarita mix or a rum and soda can easily add 20-40 grams of sugar or more to your drink, turning a low-sugar spirit into a sugary indulgence. When making low-sugar cocktails, the choice of mixer is far more important than the choice between whiskey and tequila.
Comparison Table: Whiskey vs. Tequila (Pure, Unflavored)
| Feature | Whiskey (Straight, 1.5 oz) | Tequila (100% Agave, 1.5 oz) |
|---|---|---|
| Sugar | ≈ 0 g | 0 g |
| Calories | ≈ 105 | ≈ 97 |
| Carbohydrates | ≈ 0 g | 0 g |
| Fat | 0 g | 0 g |
| Production | Fermented grains, double distilled | Fermented blue agave, double distilled |
| Flavoring | Added via barrel aging | Natural agave flavor |
Tips for Enjoying Spirits with Less Sugar
- Stick to Pure Spirits: Opt for 100% agave tequila and straight, unflavored whiskey to avoid added sugars. Check labels for any flavored or sweetened varieties.
- Choose Low-Sugar Mixers: Swap sugary sodas and juices with sugar-free alternatives like soda water, fresh lime or lemon juice, or diet mixers.
- Enjoy on the Rocks or Neat: The purest way to enjoy the flavor of a spirit without any sugar is to drink it neat or on the rocks. The water or ice adds no sugar and helps open up the flavor.
- Monitor Cocktail Mixes: Bottled margarita or cocktail mixes are often loaded with sugar. Consider making your own from fresh ingredients to control the sugar content.
- Mind Flavored Whiskeys: Popular flavored whiskies, such as honey or cinnamon variations, contain significant added sugar. Be mindful of these when trying to reduce sugar intake.
Conclusion
For those wondering which has less sugar, whiskey or tequila, the answer is a tie: both contain virtually no sugar in their pure, unflavored form due to the distillation process. The real difference in sugar content lies not in the base spirit but in the mixers, flavorings, and additives used to create cocktails. By choosing straight spirits and mindful mixers, you can enjoy these drinks without consuming excessive sugar. The key to a low-sugar drink is to focus on the preparation, not the base liquor.

Frequently Asked Questions
Q: Do all whiskeys have zero sugar? A: Unflavored, straight whiskeys contain zero grams of sugar. However, flavored whiskeys, such as honey or cinnamon varieties, have added sugar.
Q: Is 100% agave tequila sugar-free? A: Yes, 100% agave tequila is sugar-free. During distillation, the natural sugars from the agave plant are converted into alcohol.
Q: What about mixto tequilas? A: Mixto tequilas are not 100% agave and can contain added sugars, flavorings, and other additives. It's best to choose 100% agave for a sugar-free option.
Q: How do mixers affect the sugar content? A: Mixers are the biggest contributor to sugar in cocktails. Juices, sodas, and pre-made mixes contain high amounts of sugar, turning a zero-sugar spirit into a high-sugar drink.
Q: Which has fewer calories, whiskey or tequila? A: A standard shot of tequila (approx. 97 calories) has slightly fewer calories than whiskey (approx. 105 calories), but the difference is minimal.
Q: Is one of these spirits better for a keto diet? A: Both pure whiskey and 100% agave tequila are suitable for a keto diet, as they are sugar-free and contain zero carbohydrates. Just be careful with mixers.
Q: Can aging add sugar to whiskey or tequila? A: No, the aging process in barrels does not add sugar to the spirit. It imparts flavor compounds from the wood, which can create sweet-tasting notes without adding sugar.
